Black berry wine grape variety grown in Apulia

Uva di Troia n.

The Uva di Troia n. vine is one of the most prestigious and characteristic of Apulia, where it is registered among the varieties suitable for cultivation throughout the region.

Origin and Historical Outline

The Uva di Troia n. variety of black berry wine grape is one of the oldest and most characteristic of central-northern Apulia. Historical sources report that it may have originated in Asia Minor (Troia) and arrived in Apulia during the Hellenic colonization, or its name may have come from the Apulian town in the province of Foggia (Troia) or from the Albanian town of Cruja, in the popular language,  as Troia.

In the last decade, the discovery of new relatives, identified through DNA research, has made it known (Bergamini et al., 2016) that from the parents Bombino Bianco (mother) and Uva rosa antica/Quagliano, the grape varieties Uva di Troia, Bombino Nero, Impigno were obtained.
